Breakfast skipping lowered a morning artery function marker in a small trial
Among young adults who usually ate breakfast, both daily and alternating skipping patterns produced lower morning artery dilation measurements than daily breakfast.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Both breakfast-skipping patterns led to lower early-morning artery function measurements than eating breakfast daily in this small crossover trial. Fasting insulin was also higher with both skipping patterns. These are short-term physiological findings in habitual breakfast eaters; the abstract does not establish whether these patterns change the risk of future cardiovascular disease.
Only 10 healthy young adults completed the short trials. The abstract supplies no effect sizes or confidence intervals for the main comparisons, so the size and precision of the reported differences cannot be assessed here.
What researchers found
Morning artery function (%FMD/SRAUC)
On day 9, both skipping conditions had significantly lower shear-normalized flow-mediated dilation than daily breakfast. No effect size is provided in the abstract.
What the artery test measured
Researchers measured how much the upper-arm artery widened and adjusted the result for the blood-flow stimulus. This flow-mediated dilation measure assessed vascular function. The abstract provides no cardiovascular event outcomes.
How insulin fits the findings
Fasting insulin was higher in both skipping conditions than with daily breakfast. Exploratory analyses found only weak associations between artery-function changes and glucose or insulin changes, leaving the suggested metabolic explanation uncertain.
